I was working on the body and made a huge mistake. I was putting on the panel line using acrylic paint (I think this was my first mistake. Looking through the web, I should have used the enamel paint), and some went over the edge. I tried to wipe using acrylic thinner, but it just smudged it all over the white body.
Today, I worked on putting the decals on the body. I already knew this, but there are many decals on this car, and some are really big, so this was pretty challenging.
I started from the front, and used Tamiya's Mark Fit to set the decals.
Today I've made some progress on the interior. There seems to be quite a bit of differences between the challenge and the GTC, so the interior needed quite a bit ore work than I expected.
